OPERATION
When the AC circuit is initially energized, the status lamp on standard units will typically stay at full brilliance for
several hours before fading to a “dim” state, indicating the battery has charged to its normal float level.
On Spectron® equipped models, the green Status LED is iluminated when AC power is present.
NOTE: All models are supplied with an AC Lockout circuit, which prevents the emergency lights from
illuminating when the battery is connected and no AC power is present.
NOTE: All models are supplied with a Low Voltage Disconnect circuit, which prevents damage to the
battery from deep discharge during prolonged emergency operation.
⑧
NOTE: Batteries are often shipped in a discharged state – this is normal. The battery will require charging. Allow
several hours of charge before testing the unit.

Models With SPECTRON® Self-Testing/Self-Diagnostic Circuitry
Models equipped with the Spectron self-testing/self-diagnostic electronics system provide:
■ Visual indication of AC power status
Installing The Unit: Wall Or Ceiling Mount - Back Power Feed (Fig. 1)
1. Remove center ¾” KO in back plate.
2. Remove appropriate back plate KO’s for electrical box screws.
3. Feed wires through center KO and mount back plate to electrical box.
4. Attach unit housing to back plate by plastic hinge straps provided.
5. Connect building wires to transformer leads. Black and white wires for 120VAC (use wire nut to cap off red wire). Red and white wires for 277VAC (use wire nut to cap off black wire).
6. Connect red circuit board lead to (+) battery terminal.
7. Remote capacity models only: connect remote lighting load to yellow and (fused) blue pigtail leads provided.
8. The LZ2 and LZ15 may be ceiling mounted (through the back plate) by ensuring the plastic tabs in the back plate are securely attached to the front housing. In addition, the safety screw must be installed from the
outside of the housing through the reinforced boss located at the mid-point of the housing.
No. 8 security screw is shipped inserted in plastic hinge strap (see illustration above). Use pointed tool to remove KO at bottom center of unit chassis. After closing unit, install security screw through bottom KO
and tighten.
IMPORTANT: Safety security screw is not mandatory in standard wall mount application but may be installed if desired. The screw must be installed for ceiling mount.
9. To complete the installation see Final Assembly instructions on next page.

■ Visual indication of self-diagnostic test cycles
—Visual indication of any unit malfunctions including—
■ Battery fault ■ Transfer Fault
■ Charger fault ■ Emergency Lamp fault
Spectron equipped units also include:
Brownout protection: unit will automatically transfer to emergency operation upon detection of low AC power
(approximately 80% of nominal line).
Time Delay Retransfer: upon return of normal AC power, unit will remain in the emergency mode for an additional
15 minutes to allow AC power to stabilize.
LED Status Indicators
Two status indicators, one green and one red, are
provided on the control panel of all models equipped
with the Spectron option.
Green Operating Status LED
The green Operating Status LED serves as both an
AC power and a self-test indicator. During normal
operation, the green Operating Status LED will be
illuminated, indicating the presence of AC power. During all automatic or manual self-test cycles, the green
Operating Status LED will blink at a 1 Hz. rate.
Red Service Alert LED
Under normal operating conditions, the red Service
Alert LED indicator will remain “off”. In the event the
Spectron controller detects a malfunction, the red
Service Alert LED will blink at a 1 Hz. rate, based on
the following table:
Red Status LED Code
Description
One blink ON/pause
Battery not connected
Two blinks ON/pause
Battery fault
Three blinks ON/pause
Charger fault
Four blinks ON/pause
Transfer circuit fault
Five blinks ON/pause
Emergency Lamp fault
Automatic Tests
The unit will automatically initiate a self-test/self-diagnostic
cycle based on the following table:
Testing Period
Duration of Test
Once a month
1 minute
Once every 6 months
30 minutes
Manual Tests
Using the unit test switch, users can initiate
different duration test cycles based on the
following table:
Initiating Action
Test Cycle
Press test switch once
1 minute
Press test switch twice
5 minutes
Press test switch three times
30 minutes
Press test switch four times
60 minutes
Pressing the test switch at any time after a test cycle has
begun cancels the remainder of the test and returns the unit
to normal operation.
